They don't really care what passport / citizenship you currently hold. As long as you apply to the cadet program they will treat you as a Hong Kong local period. Therefore they are not going to make exceptions and shouldn't make those exceptions. I know at least one Chinese Canadian here that can't really speak that well of English and that person lived here as long as I have which is 13 years. A passport from an English country doesn't automatically mean you understand English.
PS: My gramma is the bad.
